Problems solved by technology

However, in actual production, Hydrilla verticillium will multiply in large numbers in the water after planting, and the number is difficult to control. If no intervention is carried out, it will have an adverse impact on water quality, requiring workers to remove excess aquatic plants every day.
Manual salvage of aquatic plants is time-consuming and labor-intensive, and the labor cost is high
Reduced the economic benefits of cultivating river crabs

Embodiment

[0054] 1. Crab Pond Construction

[0055] The crab pond should be selected in a place with sufficient water source, no pollution of water quality, less silt at the bottom of the pond, and a relatively secluded location. It requires convenient irrigation and drainage, electricity, and access. The size and shape of the crab pond are advisable with a standardized rectangle, and the area can be from several acres to tens of acres. The present embodiment is 10.14 acres, and the maximum water depth of the pond is 1.8 meters, which is convenient for water quality control. The bottom of the crab pond is flat, the bottom mud is preferably 10-15cm, and the bank has a certain slope, with a slope ratio of 1:3 or more. The key to the construction of the crab pond is the anti-escape facility. The commonly used anti-escape facilities are aluminum skins, which have a smooth and strong surface, and have the characteristics of long service life, convenient installation, and low price.

Abstract

The invention discloses a method for regulating and controlling the water plants of a crab culture pond, and relates to the field of water quality purification. The method comprises the following steps of silt removal and pond arrangement; pond cleaning and airing; planting of water plants; feeding of juvenile crabs, and management of the water plants; observing of water quality conditions. The method has the advantages that on the basis of the ecological culture of a river crab pond, the quantity of hydrilla varticillata is regulated and controlled by adjusting the feeding quantity of feed, and utilizing the eating condition of river crabs; the artificial regulation and control is combined with the biological self regulation and control, so that the growth of the water plants is controlled, the water quality is regulated and controlled, the cost is reduced, the feeding cost of the feed is certainly reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the field of water quality purification, in particular to a method for regulating aquatic plants in ponds for raising crabs. Background technique [0002] Hydrilla verticillata is commonly known as Wensi grass, lantern weed, shrimp grass, etc., and its scientific name is Hydrilla verticillata. It is a monocot perennial submerged plant in the family Hydrochardaceae and the genus Hydrila. It is widely distributed in ponds, lakes and ditches. Asexual reproduction begins at the end of autumn, and winter is a dormant period. Buds begin to germinate and grow when the water temperature is above 10°C. The front growth point pushes out the sediment on it, and the stems and leaves turn green when exposed to light. At the same time, with the elongation of the buds, adventitious roots germinate in the basal leaf axils to form new plants. When the plants grow up, they can be replanted with broken branches for asexual reproduction. Hydrill...
